VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 350,439, dated October5, 1886.-

Application filed August 5, 1385. Serial No. 173,623. (No model.)

To all whom it may concern:-

Be it known that I, FORDYCE ALLEN LY- MAN, of Cleveland, in the countyof Ouyahoga and State of Ohio, have invented certain new and usefulImprovements in Vapor-Burners; and I do herebydeelare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art. to which it pertains to make and usethe same.

cone or dish above the disk and embracing, the commingling-tube, with aseries of vertical j ct -orifices in the bottom of the cone fordischarging gasoline or jets of flame into the concavity of the disk,said cone being elevated 011 legs above the disk to give a free passageof air between the disk and cone to support the combustion, and also togive a greater length to the commingling-tube.

My invention further consists in a fiange or plate lying in a horizontalplane intermediate between the holes at the bottom of the cone andjet-orifices of the cap or burner above, to deflect the ascendingcurrents of hot air caused by the jets of flame at the bottom of thecone, so that these upward currents will not interfere with thehorizontal jets of flame from the burner.

My invention further consists in certain features of construction and incombination of parts hereinafter described, and pointed out in theclaims.

In the accompanying drawings, Figure l is an elevation in section of myimproved vaporburner, a portion only of the retort-tube being shown.Fig. 2 is a plan view of the same with the cone and burner removed.Fig.3 is a view in perspective of the cone, the latter being shown in aninverted position; and Figs. 4 and 5 are views of modifiedconstructions.

A represents the retort-tube, that at the bottom is connected, in theusual manner, with a supply-pipe. (Notshowa) ThistubeAatthe top isconnected with the generator, that consists of the hollow arm B and thedisk B,that are integral with each other, and with the brace-arms b andb, the latter being integral with thehorizontal arm '2) and the verticalarm If. A passage-way, 0, leads from the chamber of the tube A throughthe arms B, 1), b and b terminating in a jet-orifice-at e, presentingupward, and located directly under the commingling-tube O, the outerends of the holes drilled in forming this passage-way being closed byplugs e". The vertical tube 0 passes through a central opening in thedisk B, and is secured by the set-screw 0 The upper surface of the diskB is concaved, and has a drip-hole, B discharging into the cup E, thelatter being screwed onto the lower end of the arm I).

F is a valve operating in the arm b, for closing the passage-way c andis provided, in the usual manner, with a stuffing-box, f, and ahand-wheel or thumb-piece, f.

G is a spindle screwed into the arm I), and terminates above in aneedle-point, g, and is provided below with a lever or thumb-piece, g,for operating the spindle. This spindle in its normal position isdepressed, leaving the jet-orifices 0 open, and is usually only turnedup a few times during a season to clear the orifice when the latterbecomes obstructed. In

case the orifice should become enlarged, the

spindle, as aforesaid, is depressed, leaving the jet-orifice open H is acup or inverted cone terminating in a laterally-projecting annularflange or rim,H.

Througha central hole in the bottom of the I part H passes the tube 0;also, several vertical jet-orifices, h, pass through the bottom, andattached thereto are depending legs h, that, when the parts are inposition, rest on the disk B and elevate the cone some distance abovethe disk, enough to admita free circulation of air between these parts;also, by

elevating the cone, a greater length is had for the tube 0, for purposeshereinafter shown.

I is the cap or burner, that rests upon the cone, and has series oflateral jet-orifices, respectivelyi and i.

In operating the device, when the valve F 25 quantity of air in itspassage.

55 container made it unhandy to fill.

IO will be observed that no movable stop or defleetor is required infilling the lighting-cup. Vhen the cup E is filled, the valve F isclosed and the contents of the cup lighted, and, being directly underthe arm B and disk 13, the

r 5 flames have a broad under surface to act upon,

and the result is, the generator is quickly heated, and the gasoline inthe concavity of the arm B is vaporized; also, the connecting arms b,7), b and I) are soon heated, so that when the gasoline in thelighting-cup is burned out and the valve F is again opened, gas insteadof gasoline is discharged from the orifice c. This gas passes up throughthe tube 0, drawing in and connningling with a large This commingled airand gas is mostly discharged through the jet-orifices i and 11, where itis burned for the ordinary heating purposes; but a portion thereof isdischarged down through the orifices h, the flames from which impingethe disk 3 for heating the retort. The elevat-ion of the cone H abovethe disk serves two purposes, as aforesaid, to wit: It gives asufficient space between the cone and disk for 3 5 bringing the gases atthis part to heat the generator, and, second, it admits of a longercomminglingd ube. If the cone were depressed the length of the legs, sothat it would rest on the disk, and the com mingling-tube werecorrespondingly reduced in length, the air and gases would notthoroughly commingle in the passage through the tube G. In a variety ofvapor-burners heretofore constructed with such short commingling-tubesthis difficulty 5 was in a measure overcome by elevating the this point,would be more thoroughly commingled by the reverberator. XVith suchconstruction the result was not entirely satisfactory, and someobjectionable features were developed. The, necessary elevating of theThe force of the blast inside the burner caused a roaring disagreeablenoise, and would sometimes cause the jets of flame outside of the burnerto flicker and burn unsteady. \Vith a longer commingling-tube-say threeinches (more or less) in length, such as is shown in Fig. 1-thecontainer need be elevated only about two feet (more or less) above theburner, and with such a low head the gas passes more slowly through thetube, the length of which is such that the air and gas are well mixedwhen they enter the burner, the chamber of which thus serves as areservoir from which the gas passes out through the different orifices,giw ing steady flames and operating noiselessly.

The tube 0 might be extended below to give the required length to thesame; but this necessitates the lengthening of the arms I) and I), andany extension .of these arms would carry them farther from thegenerator, and the lower ends thereof would not be suffieiently heatedto deliver the gas at the jetorifices at the desired high temperature.

It is not at all essential that the flange 11 should be integral withthe cone H. Instead, it might be made on the bottom of the cap I, asshown in Fi 5, or might be made separate from either, as shown in Fig.4, the only essential feature being its location between thejet-orifices i and h, for the purpose aforesaid.

It is never necessary to light the gas from the orifices h, as this gaswill light itself the instant that the gas is lighted outside of the capI at the orifice 17; also, it will be observed that but one valve isrequired for operating the burner.

Vhat I claim is- 1.. The combination, with the hollow arm and disk,formed integral, the latter having a concave upper surface and adrip-hole, of burner located above the dish, a eomminglingtube extendingthrough the disk and terminating in the burner, and a conduit leadingfrom the hollow arm to a point below and directly underneath the lowerend of the commingling tube, substantially as set forth.

2. The combination, with the hollow arm 13 and disk, formed integral,the latter having a concave upper surface, of the comminglingtubepassing through the disk, the cone surrounding the upper portion of thetube and having legs or supports which rest on the concave surface ofthe disk, the vertical jetorifices formed in the bottom of the cone, andaconduit leading from the hollow arm to a point directly mnlerneath thelower end of the eommingling-tube, substantially as set forth.

3. The combination, with a generator having a drip-opening extendingthrough same, a cone seated on said generator and provided with jetorifices in the bottom thereof, a burner-cap, and a lighting-cup locatedin a posit-ion to receive the oil from the drip-opening, of acommingling-tube terminating inside of the burner-cap and a conduitleading from the generator to a point below the lower end of thecommingling-tube, substantial] y as set forth.

In testimony whereofI sign this specification, in the presence of twowitnesses, this 8th day of May, 1885.
